Explanation:

Here’s the thing—“in high spirits” means someone is really happy or upbeat. At supper, if everyone’s in high spirits, they’re probably smiling, laughing, just generally having a good time together. Let’s break down all the options:

- Option 1: *Nervous*—

This doesn’t fit. Being in high spirits is about feeling good, not worried or anxious.

- Option 2: Cheerful—

This hits the nail on the head. "Cheerful" means happy, positive, and lively, which is exactly what “in high spirits” gets at.

- Option 3: *Drunk*—

Now, sometimes people use “spirits” to talk about alcohol, but in this idiom, it’s about mood, not what’s in your glass.

- Option 4: *Anxious*—

Nope. Anxious is more about stress or nervousness, which is the opposite of being “in high spirits.”
